Bad TILES

The table below records TILES which give no/problematic signals at the output of the diffRx.  It could be due to the tile itself, the optical fiber, the SiPM, the FEE, the diffRx..... the point is that the analog signal is bad and there's nothing we can do about it.

Note that bad tiles are still plugged into readout electronics (QT), but that does NOT imply that the QT channel is bad.

Maria: Based on the online plots and previous scans.

Bad QT channels

The table below records bad QT channels.  These are channels we should not use at all.
Maria: Filled based on 2024 7 pattern test and scope tests,  where I swapped some channels and from "bad" ones it became "good" ones.

* possibly good chanel. After switching  XX to another one, XX  still did not act well in 7 pattern test
